As long as one of the files (forget which one maybe object.dat)
exists. The cgi's don't know that nagios has died. The startup rc
script clears out the the files when it is shut down so a crash on
restart should prevent the CGI's from running but that's it.

I modified my version of the script to delete the files before it
starts the daemon so a nagios or system crash followed by a "nagios
start" (without a "nagios stop") followed by a crash will cause the
CGI commands to error out.

I tried to create some patches for the cgi's that required the
datestamp in the file to be "current", but there is no standard
interval for the file to be refreshed. It depends on the polling
intervals of services etc so I gave up on that. You can find my ideas
in the ML archives if you want.
